* ASoC: Rename WM8915 to WM8996Mark Brown2011-08-081-2995/+0
| | | | | | | | | For marketing reasons the part will be called WM8996. In order to avoid user confusion rename the driver to reflect this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Acked-by: Liam Girdwood <lrg@ti.com>
* ASoC: Allow WM8915 BCLK calculation outside hw_params()Mark Brown2011-06-061-29/+53
| | | | | | | | | | | Allow more dynamic management of the device clocking by allowing BCLK to be calculated when we set SYSCLK. This means that if the system is idle when hw_params() runs then we don't try to use the SYSCLK used in that case to set up the BCLK dividers, we can instead wait until a later point such as bias level configuration. This makes it easier to manage low power modes. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
* ASoC: Error out when FLL lock interrupt is not delivered on WM8915Mark Brown2011-06-061-2/+14
| | | | | | | | | | | When the FLL locks on the WM8915 an interrupt is generated. For safety error out if we don't get that interrupt when the IRQ output of the WM8915 is hooked up. Since we *really* expect an interrupt but the threaded IRQ handler may take a bit longer than expected to get scheduled also dramatically increase the delay in this case.

* | ASoC: Use a lower detection rate when monitoring headphones on WM8915Mark Brown2011-06-021-6/+14
| | | | | | | | | | | | | | | | | | We only need to increase the detection rate to maximum if we're monitoring for button presses as the response times needed for user interaction there are much lower.

* | ASoC: Remove internally generated WM8915 suppliesMark Brown2011-06-011-7/+1
| | | | | | | | | | | | | | | | | | | | | | DCVDD and MICVDD are intended to be (and almost always are) generated by on-board LDOs which are transparently controlled by the driver so we shouldn't really be requesting them from the regulator API. If the driver is updated to support external supply of these then we will need to change the way we handle this.

* | ASoC: Support edge triggered IRQs for WM8915Mark Brown2011-06-011-2/+22
|/ | | | | | | | | | Really this should be something the IRQ core can cope with for us but since it doesn't currently do so (at least for threaded interrupts like this) do so in the driver. This allows us to run with interrupt controllers that only support edge triggered interrupts. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
* ASoC: Remove duplicate linux/delay.h inclusion.Jesper Juhl2011-05-261-1/+0
| | | | | | | | It's enough to include linux/delay.h just once in sound/soc/codecs/wm8915.c, so remove the duplicate. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
